As of May 23, West and Zampella were now in court with Activision. If West and Zampella win, they and Infinity Ward members will have royalites to the profits of MW2, about a $100 Million. Also if they win, Respawn Entertainment, a company owned by EA, will have rights to the MW series. This could mean that the profits of MW3 and BF3 will go to EA, and Activision will lose a major contributor to their profits.
I hope West and Zampella win, they deserve the profits, and MW belongs to them.
This could significantly impact Battlefield 3, because if West and Zampella win, they could shut down MW3 altogether, BF3 would have no competition, and Activision yearly earnings will be significantly reduced.
